You're missing the point. It isn't her design that is the problem, it is that her design is reflective of the problem that there is no real diversity. Wouldn't it be nice if she was one of a selection of character types? You could play the fat, horned-helmeted opera singer named Ulga or the foxy, ass-out wrestler named Mika? But that selection doesn't really exist.
Right now in SFV, if you wanted to play a man you can choose to play the focused martial artist, the cocky martial artist, the fat rocker, the DBZ wildman, the half undead dude out for revenge, the evil dictator, or the beautiful sociopath.
If you wanted to play a female, you get the wrestler with her ass out, the spec ops with her ass out, or Chun Li.
